Many baby boomers already know a thing or two about marriage and are choosing not to tie the knot on their relationships—often because of money.
U.S. Census Bureau data shows adults older than 50 are among the fastest growing segment of unmarried couples in the U.S.
Financial advisors say concerns about debt, benefits, taxes and cash flow are often the primary reasons they decide not to walk down the aisle.
"The biggest considerations couples have in deciding whether or not to remarry usually center around their children and assets," says Molly McCormack, a director of individual advisory services at TIAA-CREF.
If you're divorced and chose to remarry, you could lose alimony, pension and Social Security benefits from your former spouse. If you're widowed, you could also lose survivor's pension benefits, McCormack says.
Some couples may also want to make sure inheritances go to their own children and don't get muddled.
A partner may also be helping out adult children financially—by paying off student loans or cosigning on a mortgage—and the new partner doesn't want to take on that financial burden. In addition to mortgage, student loan and credit card debt, long-term care and medical debt are frequent concerns.
